arlzeys Patented Dec. 7, 1943 UNITED STATES PATENT OFFICE TRANSMISSIONnavrca Charles J. Dillon, New York, N. 'Y. Application March 18, 1942,Serial No; 435,241 (01. 60-54) 1 Claim.

wise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout and in which:

Figure 1 is a longitudinal sectional view through the housing of thetransmission.

Figure 2 is a transverse sectional view taken substantially on a line2-2 of Figure 1.

Figure 3 is a similar view taken substantially on a line 3-3 of Figure1.

Figure f is a longitudinal sectional view of the sectional output shaft.

Figure 5 is a transverse sectional view taken substantially on a line5-5 of Figure 1, and

Figure 6 is a similar view taken substantially on a line 66 of Figure 1.

Referring now to they drawings in detail, wherein for the purpose ofillustration I have disclosed a preferred embodiment of the invention,the numeral 5 designates the transmission casing having a liquid-tightclutch chamber 6 formed in one end thereof and a governor chamber Iformed in the opposite end thereof, the casing being of cylindrical formand composed of longitudinally split sections 8 and 9 having flanges III at the edges thereof connected by means of bolts II. p

A drive shaft I2 is journaled in one end of the casing adjacent thechamber 6 with the outer end of the shaft provided with a drive pulleyi3 driven from a suitable source of power and secured on the inner endof the shaft I2 within the chamber 8 is a clutch member ll composed of adisk I! having a plurality of blades it projecting radially on one facethereof.

A second clutch member I! of identical construction to the clutch memberI4, is secured to a tubular shaft section It with the blades l9 of theclutch member II in opposed relation with respect to the blades ll ofthe clutch member ll.

The shaft section I8 is journaled in a bearing 2| in the partition 2|separating the chambers I and I, the end of the shaft section disposedshaft 21 is journaled in a bearing 28 formed in the end wall of thecasing opposite from the pulley l3.

A pin 29 extends transversely ofthe shaft 21 and is slidably engaged inthe slot 23 of the shaft section l8.

A nut 30 is threaded on the shaft section I8 for adjustable engagementwith one end of a coil spring 3i positioned between the nut and thecollar 26 of the governor.

A collar 32 is secured to the shaft l2 and collars 33 and 34 are alsosecured to the shaft 21 to prevent end thrust of the respective shafts.

The chamber 6 is adapted to contain a quantity of liquid and uponrotation of the clutch member l4, power will be transmitted to theclutch member II, as will be apparent.

Rotation of the shaft section l8 and shaft 21 will cause actuation ofthe governor 25 resulting in 'axial movement of the shaft section l8 andadjusting the position of the clutch member ll Having thus described theinvention what I claim is:

A power transmission device comprising a casing having a drive shaftjournaled in one end and a driven shaft journaled in its oppositeend,said casing having a liquid-tight chamber therein. a hydraulic clutchelement. in the chamber and secured to the drive shaft, a tubular shaftsection slidably sleeved on the driven shaft, said fshaft section havinga slot therein, a pin carried by the driven shaft and engaged in theslot to rotatably connect the shaft section and driven shaft, a secondhydraulic clutch element in the chamber-and secured to the said shaftsection for moving the second clutch element relative to the firstclutch element, spring means urging the clutch elements toward eachother, a nut threaded on the tubular shaft for adjusting the ,tension ofsaid spring means and a governor connected to the driven shaft and tothe tubular shaft section for moving said second clutch elefment awayfrom the first clutch element upon "a predetermined rotary speed of thedriven shaft.
